Crab is a open source customized recommender engine creator which helps one to build recommender engines on the go without any high level knowledge of recommender engines.
A recommender engine can be built within few steps -
1. Load a dataset
2. Build a model using the Crab API
3. Define a similarity metric.
4. Add a recommender over it, using the Crab API
and you are done!
It has high level API and also support for well known python libraries which makes it unique and easy to use. Review collected by and hosted on G2.com.
This the only thing I prefer while building a recommender engine so I basically have no dislikes for Crab but I would like one thing to be improved, the documentation. Review collected by and hosted on G2.com.
